Biology is very similar to Tropinota hirta Poda (Coleoptera: Scarabaeidae). It swarms later in the summer and doesn’t represent as great a danger to orchards as T. hirta. However, this species can cause significant damage to flowering grapewines and late flowering wheat. They favour heavier clay soils.
